Enrichment Map Gene Sets

EnrichmentMap is a Cytoscape plugin developed in the Baderlab to help visualize, navigate and analyze functional enrichment results as generated from programs such as Gene Set Enrichment Analysis(GSEA), BiNGO, or David. Some enrichment programs, such as GSEA, allow the user to search against their own gene set database. As annotation (gene set) sources are regularly updated as new information is discovered we set up an automated system to update our gene set collections so we are always using the most up-to-date annotations.

If you use these gene sets, please cite our Enrichment Map paper.

Important Note - Genesets files from December 2011, January 2012, Februrary 2012, and March 2012 had an error in the up-propagation of GO. Up-propagation only followed the is-a relationship and did not follow the part-of relationship which translates into missing annotations. This primarily effects genesets in GO cellular compartment.

Summary

• Gene Set Files can be downloaded from : http://download.baderlab.org/EM_Genesets/

• Enrichment Map Gene Sets are a set of Gene Set files in GMT format (compatible with GSEA) updated monthly from original source locations available with:

  1. Entrez gene ids

  2. UniProt accessions

  3. Gene symbols
• The GMT File format contains one Gene Set per line. Each line contains:
  • Name (tab) Description (tab) Gene (tab) Gene (tab) ...
  • In our format:
    • Name = Gene Set Name | Gene Set Source | Gene Set Source identifier

      • Example --> ATP-dependent protein binding|GO|GO:0043008 OR arginine biosynthesis IV|HUMANCYC|ARGININE-SYN4-PWY

    • Description = Gene Set Name

      • Example --> ATP-dependent protein binding OR arginine biosynthesis IV

    • Gene = identified by one of the three possible identifiers (Entrez gene id, UniProt accession or gene symbols)

Specialty Gene Sets

• The bulk of our genesets are groupings from similar biological processes, pathways and functional annotations but there are a few additional collections of sets that we don't group with them. They include:

  1. miRs - sets consisting of all the targets for a given microRNA.

     • miR genesets are retrieved from Msigdb c3 collection.

  2. Transcription Factors - sets consisting of all the targets for a given transcription factor.

     • TF genesets are retrieved from Msigdb c3 collection.

  3. Disease Phenotype - sets consisting of all known proteins associated with the given disease.

     • Disease phenotype genesets are retrieved from the Human phenotype ontology. Genes associated with a particular disease are annotated to it. In addition, in the same style as the Gene Ontology, the relationship between each disease is stored creating an ontology of diseases. Annotations are up-propagated to related disease terms.

  4. Drugs Targets - sets consisting of all the known or predicted targets for a given drug.

     • Drug target information is retrieved from STITCH. STITCH is a resource containing the amalgamation of many different databases. A score is attached to each protein - chemical interaction. For the purpose of our genesets we only include protein - chemical interactions that have a combined score greater than 900

File Structure

< > denotes directory

• <Release> - directory is named according to date sets were updated.

  • <Species>

    • <Identifier> - (either Entrez gene, UniProt, Gene symbol)

      • <GO>

        • BP = biological process
        • MF = molecular function
        • CC = Cellular component
        • All = BP + MF + CC

        • no_GO_IEA - indicates that the file excludes GO annotations with evidence codes - 'IEA' (inferred from electronic annotation), 'ND' (No biological data available), 'RCA' (inferred from reviewed computational analysis)

        • with_GO_IEA - indicates that the file includes GO annotations with evidence codes - 'IEA' (inferred from electronic annotation), 'ND' (No biological data available), 'RCA' (inferred from reviewed computational analysis)

      • <Pathways>

      • <miRs>

      • <TF>

      • <Disease phenotypes>

• In each <identifier> directory There are amalgamated Gene Set files:

  • AllPathways - contains all pathway sources in the Pathways directory

  • GOPathways - contains all GO (MF, BP, CC) and all Pathway sources in the Pathways directory.

Creating customized Gene Sets

1. Download the desired gene set files you would like to use in your customized set and concatenate the files.
   For example, to combine Human_IOB_Entrezgene.gmt Human_NetPath_Entrezgene.gmt, you can use the following linux command:

   cat Human_IOB_Entrezgene.gmt Human_NetPath_Entrezgene.gmt > MyCustomizedSet.gmt
